Application filed February e0, 1915. SerialNo. 9,711.

To (171701 10770 it may) concern: lie it known that I, Ray A. NORTH, a citizen of the United States of America, resid-- ing at Green Bay, in the county of Brown and State of lVisconsin, have invented cer? tain new. and useful Improvements in Attachments for Beater-Bars, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to means for secur- 'ing filling material between beating bars of an engine used minanufacturing paper, and

has for its object the production of a simple and efl'iciont means whereby the filling materm] may be readily removed from between the bars or replaced whenever it should be come necessary to replace the worn filling material by new filling material.

.*\nother.ob ect of this invention is the production of a simple and "efiicient means for facilitatmg the replaclng or removal of the' filling material betwc'enthe beating bars without changing or removing the beater bars.

Other objects and advantages of the present invention will. appear throughout the following specification and claims.

In the accompanying drawings :Figure I is aperspective view of .a portion of two through the securing means-for holding the beater bars. Fig. 2 is a vertical section beater bars in an assembled position, and

also holding the fillingmaterial between the beater harsh ig. 3is a detail perspective of one of the side plates of the beater bars. Fig. 4 is a perspective view of an embodiment of the present invention wherein three beaterlbars are employed. Fig. 5'is a. trans verse sectional viewthrough a portion of the beater bars showing the manner in which the filling material is securely held between the beater bars. Fig. 6 is a detail sectional perspective of a portion of one of the beater bars showing the sockets formed therein for the purpose of receiving the retaining bolts.

'Fi-g. 7 is a detail perspective of one of the spacing sleeves'used 1n connection with the present invention. Fig. 8 is a detail perspective of a portion of one of the sheets of filling material used in connection with the present invention.

- By referring to. the drawings it will be seen that 1 designates one of the beater bars which is secured .to and held in spaced rela" tion with the other beater bar 2 by means of a spacing bolt 3. It should be understood the bolt 3.

that each of the beater bars 1 and r. isprovidecl with a notched portion 4, within which notch-ed portion i. fit the respective ends of the bolt 3. g This structure is clearly illus trated in. Fig. 1 of the drawings. A. spacing sleeve 5 is placed upon the bolt 3 and is adapted to fit between the inner walls of the beater bars 1 and 2 and hold these bars in spaced relation.

.Each beater bar is provided with; a plhrality of vertically extending notches B beater along the top edge thereof, which notcheso terminate in enlarged concave pockets 7 for the purpose ofreceivmg the conical heads 8 of the bolts 3, or the conical shaped nuts 9 of the bolts 3. It will therefore, be seen that a very simple and eiiicient means has been produced for permitting the respective bolts 3 to be placed within the notchesd and 6. Each-bolt 3 carries a threaded not .9 at

'one end, and each nut is provided with a plurality of sockets 10 for the purpose of rece ving av suitable wrench to permit the operation of the n'ut 9 and allow the nutto be firmly threaded upon the threaded arc-or This structure is clearly'siiown in Fig. 2 of the drawings.

A plurality of filler strips 11 are inter posed between the beater bars]. and 2', and

these filler strips 11 are provided with notches 12 formed near each end thereof for the purpose of receiving the end bolts 3. These filler strips 11 are also provided with apertures 13 intermediate the ends for" the purpose of permitting the intermediate bolts 3 to pass therethrough and firmly hold the filler strips 11 between the beater bars 3'. and 2. A plurality of locking bolts 14 are so cured to the beater bars 1 and 2 and are adapted to bcthreaded therethrough for the purpose ofengaging the filler strips 11 and firmly hold these filler strips in binding engagement with each other.

Each beater bar 1 and 2- 15 provided with a band receiving notch 15 upon the edge thereof for the purpose of receiving a band l8 similar to the notches 4 and 6 illustrated in Fig. 1 of the drawings for the purpose of receiving the securing bolt 19 clearly illustrated in Fig. 5 of the drawings. This bolt 19 carries a plurality of sleeves 20 which are adapted to hold the beater bars 16 in spaced relation. A plurality of filler strips 21 are interposed between the beater bars 16 and are firmly held in engagement with each other by means of the securing bolt 22 clearly illustrated in Fig. 4 of the drawings. The bolt 19 is of similar construction to the bolt 3 and carries a threaded conicalnut 22 at one end thereof for the purpose of fitting in the conical sockets formed in the inner ends of the notches 17 and 18.

This construction is similar to that shown in Fig. 1, and these beater bars 16 are firmly held in engagement with a support 24 by means of a locking band 25 which locking band fits in the notches 26 formed in the respective 'ends of the beater bars 16. It s iould be understood that the filler strips 21 fit upon the top'faee of the support 24.

It, of course. should be understood that any suitable changes in the detail mechanical eonstrin-timi may be employed without departing from the spirit of the invention so long as these changes fall within the scope of the appended claims.

It also should be understood that these beater bars may be multiplied to any extent desired. and two, three, four, five, six, or even as high as an indefinite number may be employed without departing from the spirit of the inveinion.

llaving thus described the invention what is claimed as new, is:- p

l. ln a device oi the clasihescribed the combination with a supper a plurality of beater bars. each beater ha-r provided with a plurality of notches formed therein, each notch terminating in a conical socket at its inner end. a plurality of connecting bolts fitting within said conical sockets and provided with means for snugly engaging said conical sockets. means carriedby said bolts for holding said heater bars in spaced relation. a plurality of filler strips interposed between said beater bars and provided with means for receiving said bolts wherchysaid strip will be held in detachable engagement with said heater bars. and binding means carried by said beater bars for binding said filler strips together.
